Dogs are pack animals, right? They hang around with other dogs – or humans – and exist as a constituent part of a wider entity. They like it that way. Don’t they? Or do they secretly yearn to be in monogamous relationships like humans? With just one pal? This video here suggests that maybe they do. Only the dog-on-dog jealousy here is CRAZY.

The owner of a Great Dane brings home a new puppy. But rather than welcoming the newest member of the pack, her bigger pooch gets all jelly and starts making a big fuss. It’s so cute. But at the size it is? That’s one big dog to have jumping up at you…

We all get a little jealous from time to time, so we can all empathize with this poor dog. We’re sure he’s still in for plenty of treats and love, even with the new arrival. And hey – he might even make friends with the pup eventually!
